    Package        : pypy3
    Version        : 7.3.5+dfsg-2+deb11u5
    CVE ID         : CVE-2024-6232 CVE-2024-6923 CVE-2024-7592 CVE-2024-11168
                     CVE-2025-0938 CVE-2025-1795 CVE-2025-6069 CVE-2025-8291

    This upload fixes a few of security issues in the Python standard library
    included with PyPy, an alternative implementation of the Python 3 language.

    CVE-2024-6232

        The tarfile module used to parse tar parsed header values with regular
        expressions that allowed for backtracking, which could be used to cause
        denial of service via specifically-crafted tar archives (ReDoS). Since
        tar headers have a well-known format that doesn't require backtracking
        to parse reliably, the new method of parsing only requires a single pass
        over a byte stream.

    CVE-2024-6923

        The email module didnt properly quote newlines when serialising
        email messages, which could be used to inject newlines that would
        affect the interpretation of the email headers. An attacker could
        cause some email headers to be completely skipped or potentially
        hide malicious headers within other headers.

    CVE-2024-7592

        The http.cookies, when parsing cookies that contained backslashes
        for quoted characters in the cookie value, would use an algorithm
        with quadratic complexity, resulting in excess CPU resources being
        used while parsing the value. E.g. parsing a 20000+ byte cookie
        would take about a second (ReDoS).

    CVE-2024-11168 and CVE-2025-0938

        The urllib.parse.urlsplit and urlparse functions improperly validated
        domain names that included square brackets allowing hosts that
        weren't IPv6 or IPvFuture.

    CVE-2025-1795

        In the email module, during an address list folding, when a separating
        comma ended up on a folded line and that line is to be Unicode-encoded,
        then the separator itself was also Unicode-encoded. Expected behavior
        is that the separating comma remains a plan comma. This could result
        in the address header being misinterpreted by some mail servers.

    CVE-2025-6069

        The html.parser.HTMLParser class had worse-case quadratic complexity
        when processing certain crafted malformed inputs potentially leading
        to amplified denial-of-service.

    CVE-2025-8291

        The zipfile module would not check the validity of the ZIP64 End of
        Central Directory (EOCD).
        Locator record offset value would not be used to locate the ZIP64
        EOCD record, but instead the ZIP64 EOCD record would be assumed
        to be the previous record in the ZIP archive. This could be abused
        to create ZIP archives that are handled differently by the zipfile
        module compared to other ZIP implementations. Remediation maintains
        this behavior, but checks that the offset specified in the ZIP64
        EOCD Locator record matches the expected value.

    For Debian 11 bullseye, these problems have been fixed in version
    7.3.5+dfsg-2+deb11u5.

    We recommend that you upgrade your pypy3 packages.
